From my short cycle view if low gets low enough or lasts for days the word "death" issues unbidden from my lips. Thought it came w the territory. No divinity issues here but as long as others depend on me or would even be saddened, I will not take an early exit. I wish the best for your husband health wise and suggest reasons to go on can arise unexpected when needed. PS I acan not help but look forward to my demise but am resigned to wait...heard good things come to those that do.
